Let’s see "coding better" in action. Imagine you want two tracks to crossfade based on BPM detection.

Poor approach:

Better approach using event-driven principles: mixpad code better

Result: Seamless, phase-coherent mixing that sounds professional and uses 5% of the CPU of the polling method.

To achieve better MixPad code, the architecture must strictly separate concerns. /mixpad_project/ /src/ main

Use gettracks to know how many tracks exist before referencing track 5.

When you code better in Mixpad, you’re not just writing for the compiler; you’re writing for the next engineer (or yourself in six months). Let’s see "coding better" in action

Wrap your DSP loops in try-catch blocks (or your language’s equivalent). If a single sample calculation fails, you want to mute that track, not crash the entire mix engine.

Example:

function process_track(track_id):
  try:
    apply_filters(track_id)
  catch OutOfBoundsError:
    mute_track(track_id)
    log_error("Track track_id had bad data")
    return silence

// Use SIMD to perform parallel operations on audio samples
void processAudioSamples(float* samples, int numSamples) 
  __m128 sampleVec;
  for (int i = 0; i < numSamples; i += 4) 
    sampleVec = _mm_loadu_ps(&samples[i]);
    // Perform SIMD operations on sampleVec
    _mm_storeu_ps(&samples[i], sampleVec);
